Specification of Letters Patent.

Application filed September 3, 1912.

Patented Feb. 3,1914. Serial No. 718,290.

To aZZ whom it may concern Be it known that I, OSCAR W. Hanson, acitizen of the United States, residing at the city of Topeka, in thecounty of Shawnee and State of Kansas, have invented certain new anduseful Improvements in Machines for Making Paper Boxes, of which thefollowing is a specification.

The present invention relates to machines for making papenboxes and moreparticularly to machines designed for producing the enveloping portionof a sliding receptacle carton, the primary object of the presentinvention being the provision of a machine, which simultaneously feedsthe blank forming the body of the box and the wrapper which is securedthereto by means of an adhesive, the adhesive strip being held inposition for the reception of the blank, both to be projected to arotating box-forming mandrel, which receives the forward edge of theblank and the adhesive strip and, in connection with a novelform ofcam-operated mechanism, bends the blank to assume a hollow rectangularenvelop while the blank is being fed forw rdly, the inclosing adhesivestrip continuing to be wrapped upon the stiff blank pcrtion'upon theretraction of the blank-feeding mechanism, so that a double thickness ofadhesive strip is wound upon the envelop before the ejection or movementof the finished envelop from the mandrel.

A further object of the present invention is the provision of means,during the rotation of the mandrel and the formation of the blank andadhesive strip, for tucking in or folding the projecting edge of theadhesive strip, so that, when the completed article is moved from theforming portion of the mandrel, such folded or tucked in portion will beprojected within the envelop to be held therein to form a finished edgeat one end of the envelop.

A still further ob'ect of the present invention is to provide a novelform of blank and adhesive strip feeding mechanism, whereby the blank isfed its full distance upon the forward stroke thereof, while theadhesive strip is fed both upon the forward and the retracting stroke,so that substantially double the length of adhesive strip is employed ineach box envelop.

relatively to the length of the cardboard blank used for forming thestiff portion of the box envelop.

A still further object of the invention is the provision of the novelconstruction of actuating mechanism for severing the ad hesive stripjust prior to the projection of a new blank of cardboard, whereby theadhesive strip is in reality serrated transversely, in order to be tornby the rotation of the mandrel at the desired point, so that thecompleted article will have the adhesive strip folded in proper relationto the cardboard, so as to envelop the same and prevent any rough edgesfrom protruding.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed with out departing from the spirit of the invention.

In the accompanying drawings forming part of this specification, inwhich like num bers of reference denote like parts wherever they occur,Figure 1 is a tpp plan view of the complete machine, the adhesivestripengaging-and-feeding mechanism not being shown; Fig. 2 is alongitudinal sectional View on line 22, Fig. 1; Fig. 3 is an endelevation with the power transmitting wheel removed, taken from the leftas viewed in Fig. 1; Fig. 4 is a sectional view on line 44, Fig. 1; Fig.5 is an enlarged detail sectional view on line 5--5, Fig. l, the mandrelbeing in the position it assumes when initially receivin the blankadhesive strip; Fig. 6 is a sectional view on line 6(), Fig. 1; Fig. 7is an enlarged detail perspective view of the main portion of themandrel, showing the clamping mechanism and ejecting mechanism justprior to the ejecting of the finished envelop; Fig. 8 is a sideelevation of the mandrel adjacent to the envelop-ejecting mechanism, thesliding sleeve being shown in section; Fig. 9 is a sectional view online 99, Fig. 8; Fig. 10 is a sectional view on line 10-10, Fig. 4; Fig.11 is a detailed sectional view of a portion of the mandrel, with thecreasing or folding blade in operable relation; and Fig. 12 is anenlarged detail sectional view through a portion of one of the boxcovers or envelops, showing the finished end after ejection from off themandrel.

In taking the case for detailed description, the same will be consideredunder four headings, namelythe frame, which includes the drive shaft,operating cams, and the blank-containing hopper; theblankand-adhesive-paper-feeding mechanism; theblank-and-paper-guide-and-forming mechanism; and the paper-cuttingmechanism.

The frame-Referring to the drawings, the numeral 1 designates the mainframe or support of the machine, which frame has mounted thereupon thethree shaft-carrying supports or journals 2, 3, and 4, the two supports2 and 3 being provided with two vertically alined journals, while thesupport 4 is provided with a single journal, whereby the main shaft 5 isproperly supported in the lower journals of the two supports 2 and 3 andthe only journal of the support 4, such shaft being disposedlongitudinally of the machine and operated through any well known meanspreferably connected at the left end thereof as viewed in Fig. 2.

In order to operate the various mechanisms, mounted upon the main shaftare the respective cams 6, 7, 8, 9, 10, 11,. and 12, thus operating allof such mechanisms directly from the main shaft, while keyed upon androtatable with the main shaft is the large gear or pinion 13, which ispreferably of twice the diameter of and meshes with the small gear orpinion 14, keyed upon the counter shaft 15, which is journaled in theupper journals of the two brackets or supports 2 and 3 and carries themandrel M, the detailed description of which will appear later on.

Mounted upon the main frame to the rear of the shaft 5and substantiallycentrally of the machine, is the supporting plate 17, to which isconnected and carried the base plate 18, on which at its forward end adjcent to the mandrel M is carried the blank hopper 19, which contains theblanks B of cardboard or the like, said blanks being preferably scoredat the points where same are to be folded and being out to the properlength and so positioned within the hopper as to have the same fed oneat a time from the bottom thereof, the weight 20 assisting in suchfeeding as will presently appear.

B Zcmlc-aacl-aclhesoe-pape-r-fee(Zing mechanism.This mechanismcomprises, essentially, the reciprocatory lever or arm 21, which ispivoted in the lug 22 mounted upon the base plate 1 of the machine, thesame being operably disposed and held in engagement with cam 7' by meansof the spring 51, so that the rotation of the cam will impart thedesired outward movement to the lever 21 to pull upon the rod 23 whichis adj ustably connected by means of the pin 24 in the elongated slot 25of the blank-andadhesive-strip-feeding lever 26. The lever 26 isfulcrumed at its lower end to the frame 17 as at 27, while its upper endis forked as at 28 and has adjustably mounted therein the pin 29 of thearm 30, said arm 30 being connected at 31 to theblank-and-adhesivestrip-feeding plate 32. This plate 32 is mounted forreciprocation between the guides of the base plate 18 and is providedwith the reduced paper-blank-engaging end having the abrupt shoulderedportion 33 upon the upper face thereof, so that upon the forwardmovement of the plate 32 the lower blank B within the hopper 19 willassume the position as shown in Fig. 5'and be propelled through theaperture at the lower end of the hopper 19 and below thespring-depressed gate 35, whose lower end is chamfered as at 86 topermit the passage of the blank when propelled out of the hoper by theplate 32, but which upon the retraction of the plate 32 will snapdownwardly to prevent the accidental passage of another blank, until theplate-32 has assumed the dotted line position as depicted in Fig. 5.

The rear extension 37' of the plate has connected thereto thepaper-feeding clampactuatmg plate 38, whose rear. end 1s pivotallyconnected to the operating arm 39 of the pivoted paper-clamping arm 40,said arm 40 being connected at 41' to the upper free end of the lever42, which as shown has its lower end pivotally connected at 43 to thelower end of the rigid support 41 7 carried by the paper-guiding plate49. The pin 46 is carried by the arm 42 and is disposed for coactionwith'the lowercurved end 45 of the strip-engaging clamp 40 upon theforward movement of the plate 32, the rearward movement thereof not onlyreleasing said clamp, but, also, moving the arm to the position as shownin Fig.3. The strip of paper 47 is fed from any source belowtheadhesive-applying device 48 and over the pin 46 by the movement ofthe plate 32 forwardly, due to the engagement of the cam to movethelever 21 thus moving the blank from the hopper and at the same timefeeding the adhesive strip over the plate 49 through the guide 50disposed below the base plate 18 and between the clamping rollers 58 and60, the detaileddescription of which will appear later.

The spring 51, which holds the lever 21 in engagement at all times withthe cam 7 and retracts the plate 32 to the position as shown in Fig. 1,is connected to the upper end of the lever 21 and by means of the eye 53is connected to the standard or plate 17 of the frame of the machine. Bythis construction, it will be seen that the rotation of the shaft 5 willrotate the cam 7 and conse quently impart the desired movement to thelever 21, the larger portion of the cam forcing the lever 21 from theposition depicted in Fig. 1 to the position as shown in Fig. 5, thisaction as before stated feeding the lower blank B into the envelop orbox-forming position and, simultaneously therewith, the adhesive strip47, the retracting action of the lever 21 moving the plate 32 in theopposite direction to the dotted line position Fig. 5, simultaneouslyreleasing the paper adhesive strip clamp 40, but permitting said stripto be moved and at the same time permitting the strip 47 to be pulledand wrapped upon the formed envelop upon the mandrel M, as will laterappear.

BZan/c and Paper Guide and -F0rmz'ng flfecham'sm.At the initial startingof the machine, the extreme end of the adhesive strip 47 normally restsbetween the rollers 58 and 60, so that upon the projection of the blankB from the hopper 19 by the feeding plate 32, the forward edge of saidblank will be brought between said rollers 58 and 6() and by theimpingement thereof will engage the end .of the strip 47, the adhesiveside thereof being disposed upwardly and thus being engaged by adhesionto the blank B and carried forwardly between said rollers to the mandrelM, the parts at this period being in the position as clearly shown inFig. 5.

The lever or arm 55, which controls the actuation of the lower clampingroller 58, is keyed upon the shaft 54, which extends between thebrackets B and B and is the lowermost shaft. A radial arm 56 is rigidlysecured to shaft 54 and is connected to the spring 57, which normallypulls arm 56 downwardly and consequently holds the roller 58 upwardly,the cam 11 carried upon the shaft 5 being the operating cam for thelever 55 as will later appear.

Connected to the forward end of the baseplate 18 adjacent to the outletof the hopper 19 are the two brackets 59, between which is journaled theupper roller 60, the roller 60 being provided with the peculiarly shapedsurface as clearly shown in Fig. 1, that is with a plurality of enlargedand reduced portions a and 0, respectively, so as to provide the propercontact surface for the blank B and strip 47 during its projectionthereof to the mandrel M, andat the same time not have sufficientsurface to retain any too great amount of the adhesive from the strip47, that might interfere with the feeding of the blank strip to saidmandrel.

The mandrel M consists, primarily, of the main forming block 61, towhich is pivoted the fiat-engaging-and-clamping member 62, the adjacentfaces of the same being cut at an angle as clearly shown in Figs. 4, 5,and 9, and providing, as before stated, when the mandrel is in theposition as shown in Fig. 5, the receptacle for the forward projectingend of the blank B and strip 47, the mandrel being in such position toreceive the edges at the initial projection of the blank and strip. Themandrel M is rotated continuously with the shaft 15, and, as the gear 14is of substantially one-half the diameter of the gear 13, such shaft 15is rotated at twice the speed of the shaft 5, so that the mandrel M isrotated two full revolutions during one reciprocation of the lever 21and the paperfeeding plate 32.

Formed integrally with the mandrel is an inclined arm 63, which has apin or journal 64 mounted in the upper end thereof to which. ispivotally connected the arm 65, which carries the clamping portion 62 ofthe mandrel and permits the same to swing to and from the main portion61 of the mandrel, to permit the insertion and withdrawal of the innerflap of the blank B and strip 47, at the initial projection of the same,and at its final movement from the forming portion of the mandrel. Inorder to impart such movement to the clamping member 62, an arm 66 isconnected rigidly t0 the arm and projects so that its free end 72 willengage lug or cam projection 73, such engagement, as viewed in Fig. 8,holding the clamping member 62 down upon the inserted portion of theblank and adhesive strip during the twirling of the mandrel and beforethe ejection of the finished blank from the forming portion of themandrel. A sprin 67 is preferably arranged to hold the free end 72 ofthe rod 66 down upon the cam 73, so that any depression of the free endthereof will permit the lifting of the clamping jaw 62 from the mainportion 61 of the mandrel.

Slidably mounted upon the inner end of the shaft 15 adjacent to themandrel M, is a spool which carries the cam 73, the projection 69, andthe two blank-ejecting plates 68 and 68, both of which plates are somounted as to slide upon the wider portions of the mandrel M to assumethe position as shown in Fig. 7 when the blank is being twirled upon themandrel, or to be moved forwardly to project adjacent to the spacingslot 83 of the mandrel when ejecting the completed blank from the sameupon the auxiliary-forming end 84 of the mandrel and before the finalejection thereof from the machine.

In order to operate the ejecting mechanism, and consequently operate theclamping portion 62 of the mandrel, a yoke 71 engages the spool 70 andis itself carried in the upper end of the arm 75., which arm ispivotally connected at 7 6 to the base plate of the machine. This arm 75carries inter mediate of its ends a pin 77, which rides within the camgroove 78 of the cams 10, such groove being so formed as to impart tothe spool 70 at the proper time the movement from that shown in Fig. 7to the finished blank-ejecting posit-ion as before stated, and justprior to the introduction of a new blank into the cutting portion of themandrel it is returned to the position as shown in Fig. 7. Thus, the arm75 will be oscillated or reciprocated longitudinally of the machine asviewed in Figs. 1 and 2.

In order that the adhesive strip 47 may be folded in so as to cover therespective ends of the blank when formed into the envelop, the saidstrip will be wider than the blank and when fitted upon the mandrel andtwirled thereupon will have one edge projecting over the slotted portion83, so that the folding blade 81 will be moved at the proper time, fourtimes to each revolution of the shaft 15. This folding blade 81 iscarried in the upper end of the operating lever 82 and is actuated bythe cam 9, which is provided with a plurality of cam surfaces, so thatfour movements for every revolution of the shaft 5 are imparted to theupper free end of the lever 82 toward and from the mandrel M. This lever82, as before stated, is pivoted to the main frame at 79 and is providedwith a spring 82, which normally holds the lever into engagement withthe cam surface, the folding blade 81, as clearly demonstrated in Fig.11, being moved toward the mandrel by said spring and away therefrom bysaid cam. This movement is so timed that, when the straight sides of themandrel are perpendicular to the baseplate of the machine, the foldingblade 81 will be thrown into the groove 83 of the mandrel, and therebycrease the adhesive strip'47, as clearly illustrated in Fig. 11, sothat, when the mandrel has been rotated two full revolutions, the foursides of the mandrel have been presented to the folding blade 81 and theedge of the strip 47 has been turned in.

At the extreme right, as viewed in Fig. 2, the blank will have beenprojected in the slot 83, so that, when the ejector plates 68 and 68have been moved to the right, as viewed in Fig. 7, the blank remainingupon the forming portions of the mandrel, consisting of the portions 61and 62, will be moved to the right and upon the final form ing portion84 of the mandrel, which will project the right angled edges turned inby the folding knife 81 and, as viewed in Fig. 12, so that the blankwill rest upon the portion 84 of the mandrel, and by the next succeedingblank will be forced over the enlarged end 85, which slightly expandsthe blank and makes it easy for the introduction of the receptacleportion of the carton.

In order to finish the box after the movement of the same by the ejectorplates 68 and 68 upon the mandrel portion 84, the roller 86 is provided,this being termed the finishing roller. In order to properly operatethis roller, the arm 87 which carries the same is keyed upon the shortshaft 88 so that the arm 89 of said arm or lever 87 will be pulleddownward by the spring 90 and consequently hold the finishing roll 86upward. In order to positively move the said roller 86 downwardly uponthe mandrel during the finishing of the envelop, the arm 91, connectedto the shaft 88, has its roller 92 in engagement with the cam 6 upon themain shaft 5. This cam is so constructed as to impart a positivemovement against the action of the spring 90, and thus at the propertime place the finishing roller 86 into engagement with the exterior ofthe man drel portion 84 and thus smooth or finish the receptacle orenvelop before its final ejection.

In order to properly press the blank and adhesive strip 47 upon theportions 61 and 62 of the mandrel M during the twirling action andfolding of the blank and strip thereupon, the roller 93 is carried inthefree end of the lever or arm 94, which is keyed upon the shaft 95,which is above but out of line with the shaft 54, which act-uates, asbefore stated, the roller 58. The arm 96 is keyed upon the shaft 95 andhas a spring 97 attached thereto, which spring exerts a tension to holdthe roller 93 up to and in engagement with the mandrel M, but in orderto impart the desired movement to the roller 93, the arm 98, whichis'connected at the extreme end of the shaft 95, as viewed at the leftin Fig. 1, is provided with a roller 99, which is held in engagementwith the cam 12 by the pull of spring 97 and is thereby actuated by saidcam during the rotation of the shaft 5.

The roller 58 is actuated through the medium of the shaft 54, as beforedescribed, which shaft 54 is controlled by the spring 57 which normallyexerts a tension to hold the said roller upwardly and into engagementwith the coacting roller 60, which is a fixedly journaled roller. Inorder to impart to the roller 58 the desired movement to and fro-m theroller 60, the arm 102, connected to the extreme end of the shaft 54, asViewed in Fig. 1, carries the roller 103, which is in engagement at alltimeswith the cam 11, which is the actuating cam for the roller 58.

the position, as clearly shown in Fig. 5, and

- upon the mandrel, whose adhesive strip por- From the description, itwill be seen that, after the blank-and-adhesive-strip-feeding mechanismis operated, the mandrel being in the clamp 62 being spaced from themain portion 61, so that the forward end of the blank and adhesive stripis projected there between, as illustrated in Fig. 5, a rotary action isimparted to the mandrel, thus twirling the blank and strip thereuponwhile the cam 12, which actuates the forming roller 93, will impart anupward movement to said roller 93 and bring it into engagementat theproper time with the mandrel, thus rolling and properly folding theblank and adhesive strip about the forming portion of the mandrel duringthe two complete revolutions of the same. At the final rotation of theblank and strip and after the said adhesive strip has been out, as willlater appear, the cam 10 will cause the yoke 71 to be moved to theright, as viewed in Figs. 1,

upwardly and toward upper feeding roller 60. This cutting edge 2, and 7,thus moving the ejectors 68 and 68 into engagement with the blank formedtion, as before stated, has been folded in by the folding blade 81 andupon the receiving portion of the mandrel, the cam 73 being releasedfrom the free end 72 of the rod 66, so as to permit the easy withdrawalof the flap impinged between the clamping portions of the mandrel.

The return of the ejecting plates 68 and 68 is very rapid so as not tointerfere with the introduction of the next blank and adhesive strip tothe clamping portion of the mandrel, while after the blank has beenplaced upon the portion 84 of the mandrel the finishing roller 86 willbe actuated to engage the same upon the portion 84 and thus roll 'out orcrease the same before the final ejection of the finished blank over theenlarged end 85 of the mandrel, upon the next succeeding operation ofthe ejecting plates 68 and 68.

Paper-cutting mechanism-.-In order to out the adhesive strips at theproper time, that is, after a strip 47 substantially twice the length ofthe blank B has been presented and about to be completed or wound uponthe mandrel M, a standard 104 is mounted upon the said plate and hasjournaled in the upper end thereof ashortshaft 105, which has keyedthereto a sleeve 106, which has formed integrally therewith therearwardly extending arm 107, which is connected spring-tensionedly tothe base plate 1 by means of the spring 108, said spring 108 having atension to pull downwardly and thus lift the lever or arm 109 so thatits roller 110 will be held in engagementat all times with the peripheryof the operating cam 9, this operating cam 9 being provided with aperiphery which at the proper time 1 will permit the lifting of theknife carrying arm 111, so that the plate 112 carrying the blade 113will introduce the cutting edge 114 the fixedly journaled 114 isserrated to correspond to the irregular surface of the roller 60, sothat the teeth of said serrations will enterthe grooves of the roller60, and thus properly perforate the paper, so that the continued pullingaction of the mandrel will tear the paper while the blade is holding thesame, the roller 58 beingdrawn into engagement with the paper so as toretain the remaining portion thereof while the next forward edge of theadhesive strip 47 is in proper position to be engaged by the next blankB as the latter is moved forwardly out of the hopper 19.

From the foregoing description taken in connection with the drawings, itis evident that with a machine constructed according to the presentinvention, that the blank B will be properly introduced into thegripping portion of the mandrel M and with it carry the adhesive strip47 and by reason of the cam and spring actuated mechanisms, the saidblank and adhesive strip will be properly wound or formed upon themandrel, the blank being sufficiently long to permit a full rotation ofthe mandrel to complete the forming thereof, while the adhesive stripwill continue to be wound upon, the same for another complete revolutionof the mandrel, to be properly severed at the proper time, and justprior to the ejection of the blank by the ejectors 68 and 68.

The operation of the machine will be readily understood from the aboveand needs no further description.

While the machine of the present invention is primarily adapted forproducing the enveloping portion of a sliding carton, yet it should beunderstood that, mutatz's mutanciz's, same may be adapted for producingthe neck portion of a carton.
